How do I make a nested slider in drupal 7?

Hello,

I want to make a nested slider similar to the one found on Military.com.

I have tried using slick carousel but, the only supplementary module to enable nested slider functionality for the slick carousel module is slick paragraphs and it is only available for drupal 8.

Any suggestions for making a nested slider in drupal 7?

Thanks.
